Abstract
The utility model discloses an oxygen lance muzzle sealing device which comprises a top cover (1), a movable cover plate (2), a sealing base (3), a plurality of air inlet pipes (4) and a structural steel beam (6), wherein the top cover (1) is sheathed on the outer wall of an oxygen lance (5); the air inlet pipes (4) are fixedly connected with the sealing base (3); and the movable cover plate (2) is fixedly connected with the structural steel beam (6). When the top cover descends to the movable cover plate along with the oxygen lance, nitrogen or steam enters the sealing base through the air inlet pipes, and then enters an oxygen lance muzzle at high speed through gaps to be ejected out, thus preventing smoke dust generated in a converter from escaping. The oxygen lance muzzle sealing device has simple structure, is economical and applicable, and is safe for use and convenient for operation.
Description
Technical field
The utility model relates to a kind of tightness system, especially a kind of excessive tightness system of converter oxygen gun mouth flue gas that prevents.
Background technology
At present, in the converter steelmaking production process, people reduce environmental pollution in order to prevent from the excessive flue dust in converter oxygen gun mouth position, take following several method usually:
Method one, hollow annulus of fixed installation directly over converter oxygen gun mouth position, internal radius is identical with oxygen muzzle internal diameter, the hole of opening several downward-sloping certain angles on circle ring inner wall equably.When the decline of oxygen rifle begins to blow, in each hole, spray nitrogen.This method not only consumes a large amount of nitrogen, and it is very undesirable to suppress the excessive effect of flue dust.
Method two, sealing socket of fixed installation directly over converter oxygen gun mouth position, awl dish of cover on oxygen gun body, the awl dish can be along with oxygen rifle free lifting, and by four baffle plates, the awl dish is fixed on the oxygen gun body.Awl dish inwall is identical with oxygen muzzle internal diameter, difference uniform distribution circular hole on awl dish inwall and the outer wall, in the time of when the awl dish drops to sealing socket with the oxygen rifle directly over, sealing socket inwall circular hole is corresponding with awl dish outer wall circular hole, nitrogen enters in the awl dish by circular hole in sealing socket, sprays by the circular hole on the awl dish inwall.This method can reduce the nitrogen consumption, but because the awl dish can not overlap fully with hole on the sealing socket, it is undesirable to cause suppressing the excessive effect of flue dust.
The utility model content
It is a kind of safe in utilization, easy to operate that technical problem to be solved in the utility model is to provide, and can prevent effectively that converter oxygen gun mouth flue gas is excessive, can reduce the converter oxygen gun mouth sealing device that nitrogen consumes again.
The utility model is achieved in that the sealing device comprises top cover, removable cover, sealing socket, several inlet pipe and steel structure girder, and top cover is sleeved on the outer wall of oxygen rifle, and inlet pipe is fixedlyed connected with sealing socket, and removable cover is fixedlyed connected with steel structure girder.
When top cover drops on the removable cover top, and the space is arranged between the removable cover.
Between removable cover and the sealing socket top hollow joint is arranged.
Sealing socket comprises sealing-ring loam cake, sealing-ring base and slit between the two, and the sealing-ring loam cake is fixedlyed connected with the sealing-ring base.
Top cover is made up of steel plate and several preset piecess of center drilling.
The removable cover end face is the flat board of band circular hole in the middle of, connects hollow steel pipe below.
Inlet pipe can be advanced nitrogen, also can advance steam.
The utility model can prevent effectively that converter oxygen gun mouth flue gas is excessive, can reduce the consumption of nitrogen again, and inlet pipe also can make full use of the steam that the converter waste heat boiler produces, and realizes energy-conserving and environment-protective.
